Question

我在django中写了自己的评论系统，但我不知道它是否是实现这一功能的正确方法。评论样式就像是facebook，因此您有一条评论和与该评论相关的回复。请查看我的代码。

models.py

class Comment(models.Model):
    blog = models.ForeignKey(Blog, on_delete=models.CASCADE)
    user = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    message = models.CharField(max_length = 250)


class CommentReply(models.Model):
    whichcomment = models.ForeignKey(Comment, on_delete=models.CASCADE)
    user = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    message = models.CharField(max_length = 250)
    blog = models.ForeignKey(Blog, on_delete=models.CASCADE)

views.py

def PostDetail(request, pk):
    form1 = CommentForm
    form2 = CommentReplyForm
    data1 = Blog.objects.get(pk=pk)
    com = Comment.objects.filter(blog=data1)
    replycom = CommentReply.objects.filter(blog=data1)

如果request.method ==＆＃39; POST＆＃39;：

if request.POST.get('whichcomment'):
    data3 = CommentReplyForm(request.POST)

    if data3.is_valid():
        whichcomment = int(request.POST.get('whichcomment'))
        message = data3.cleaned_data['message']

        CommentReply.objects.create(
            whichcomment = Comment.objects.get(id=whichcomment),
            user = User.objects.get(username=request.user.username),
            message = message,
            blog=data1

        ).save()

        return HttpResponseRedirect(reverse('postdetail', args=(), kwargs={'pk': pk}))
        #return render(request, 'postdetail.html', {'data1': data1, 'form1':form1, 'com':com, 'form2':form2, 'replycom':replycom})


else:
    data2 = CommentForm(request.POST)

    if data2.is_valid():
        blog = data1,
        message = data2.cleaned_data['message']


        Comment.objects.create(
            blog=data1,
            user= User.objects.get(username=request.user.username),
            message=message
        ).save()

        return HttpResponseRedirect(reverse('postdetail', args=(), kwargs={'pk': pk}))

否则： return render（request，＆quot; postdetail.html＆＃39;，{＆＃39; data1＆＃39 ;: data1，＆＃39; form1＆＃39;：form1，＆＃39; com＆＃39;：com，＆＃39; form2＆＃39;：form2，＆＃39; replycom＆＃39;：replycom}）
